Core Skills Analysis
Science
- Will practiced scientific observation by examining unhealthy squash leaves and using the Picture This app to identify powdery mildew.
- He learned that powdery mildew is a fungal plant disease and connected visible leaf symptoms with a biological cause.
- Will applied a disease-management strategy by pruning dead or heavily affected leaves to reduce damaged plant material.
- He explored how a 1:9 milk-to-water spray may help reduce fungal spores, linking a household material with plant-care science.
Tips
Tips: Turn this experience into a mini investigation by having Will photograph the squash leaves before treatment and at regular intervals afterward. He can record the date, leaf condition, weather observations, and treatment used in a simple garden journal. Invite him to compare treated and untreated leaves only if it can be done safely and without spreading the disease, then create a labeled drawing showing healthy tissue, damaged tissue, and fungal growth. Finally, have Will research why pruning and sprays can help manage plant diseases and write a short evidence-based conclusion about which observations support his results.

Learning Standards
- Virginia SOL Biology BIO.2: Will connected plant health with biological processes by identifying powdery mildew as a fungal disease and considering how treatment may affect fungal spores.
- Virginia SOL Grade 1 Science 1.1: The activity reflects scientific practices through observation, use of a digital identification tool, problem identification, and application of a suggested solution. This standard is elementary-level, but the practices remain relevant to Will’s investigation.
